Abstract

Disclosed herein are a method, an apparatus, and a storage medium for image encoding/decoding using partitioning. Various prediction methods and prediction modes may be used for prediction of a block. When a block is partitioned, information related to partitioning, such as information indicating whether partitioning is to be performed and information specifying the type of partitioning, is signaled. Also, when partitioning is applied to the block, an available prediction method and an available prediction method in prediction for the block may be restricted in prediction for the block. For optimization of signaling, multiple pieces of information related to prediction may be signaled, wherein the pieces of information may have dependency relationships, and in some cases, additional information may be derived as specific values depending on the value of one piece of information, and signaling of the additional information may be skipped. There can be provided various methods for efficiently signaling multiple pieces of information based on the restrictions and dependency relationships.
